  2. Field of view - Wikipedia

    en.wikipedia.org/wiki/Field_of_view

    Angular field of view is typically specified in degrees, while linear field of view is a ratio of lengths. For example, binoculars with a 5.8 degree (angular) field of view might be advertised as having a (linear) field of view of 102 mm per meter. As long as the FOV is less than about 10 degrees or so, the following approximation formulas ...

  3. Angle of view (photography) - Wikipedia

    en.wikipedia.org/wiki/Angle_of_view_(photography)

    A camera's angle of view can be measured horizontally, vertically, or diagonally. In photography, angle of view (AOV) [1] describes the angular extent of a given scene that is imaged by a camera. It is used interchangeably with the more general term field of view.

  4. Field of view in video games - Wikipedia

    en.wikipedia.org/wiki/Field_of_view_in_video_games

    A field of view. In first person video games, the field of view or field of vision (abbreviated FOV) is the extent of the observable game world that is seen on the display at any given moment. It is typically measured as an angle, although whether this angle is the horizontal, vertical, or diagonal component of the field of view varies from ...

  5. Visual field - Wikipedia

    en.wikipedia.org/wiki/Visual_field

    The binocular visual field is the superimposition of the two monocular fields. In the binocular field, the area left of the vertical meridian is referred to as the left visual field (which is located temporally for the left, and nasally for the right eye); a corresponding definition holds for the right visual field.

  6. Perspective distortion - Wikipedia

    en.wikipedia.org/wiki/Perspective_distortion

    Perspective distortion takes two forms: extension distortion and compression distortion, also called wide-angle distortion and long-lens or telephoto distortion, [1] when talking about images with the same field size. Extension or wide-angle distortion can be seen in images shot from close using a wide-angle lens (with an angle of view wider ...

  7. Perceived visual angle - Wikipedia

    en.wikipedia.org/wiki/Perceived_visual_angle

    Accordingly, as described below, the visual angle θ is the difference between two real (optical) directions in the field of view, while the perceived visual angle θ′, is the difference by which the directions of two viewed points from oneself appear to differ in the visual field.

  8. Visual angle - Wikipedia

    en.wikipedia.org/wiki/Visual_angle

    Visual angle is the angle a viewed object subtends at the eye, usually stated in degrees of arc. It also is called the object's angular size . The diagram on the right shows an observer's eye looking at a frontal extent (the vertical arrow) that has a linear size S {\displaystyle S} , located in the distance D {\displaystyle D} from point O ...

  9. Optimum HDTV viewing distance - Wikipedia

    en.wikipedia.org/wiki/Optimum_HDTV_viewing_distance

    Horizontal, vertical and diagonal field of view. It has been demonstrated that viewing a display that occupies a greater visual angle (also referred to as field of view) increases the feeling of presence. [6] More importantly, the wider the visual angle (up to a plateau at approximately 80 degrees), the greater the feeling of presence. [8] [9]
